Excerpt from Proceedings of the American Philosophical Society, Vol. 39: Held at Philadelphia for Promoting Useful Knowledge Attacid genera are more modern than the diurnals, which they thus clearly outrank. Now the indications of the base of the median system, the presence of cross-veins, the forking of the radius of hind wings, are primitive or Tineid characters, and the conclusion is here again irresistible, the diurnals are nearer to the Tineid trunk of the lepidopterous tree than the Attacinae, because they retain more generalized features in the neuration. I think these considerations should divert the general prepossession that the butterflies are the final product of the lepidopterous tree, or that this corresponds in reality with Dr. Packard's plan, which, with all allowances, appears to be still governed by this idea.
